This running shirt design guide covers everything from seam types to ventilation technologies. When sourcing custom running shirts, fabric is only half the story. The design details—how the shirt is constructed, where seams go, what kind of ventilation it uses, and how logos are applied—can make the difference between a product runners love and one they leave in the drawer.
This guide covers running shirt design styles, ventilation technologies, logo placement options, and the pros and cons of each—with practical advice for brands at different order volumes.
Running Shirt Design Guide: Why Design Matters
Running shirts face unique demands. They need to handle high sweat output, repetitive motion, and constant exposure to the elements—all while staying comfortable and chafe-free. Design features that work on a casual tee often fail on a running shirt.
Two factors matter most for comfort: seam type and fabric type, followed by fit. If the seams rub, the shirt irritates. If the fit is wrong, it restricts movement. And if there’s no ventilation where it counts, runners overheat.
Key Design Features in Running Shirts
Seam Construction
Seams are the #1 source of chafing in running apparel. Here’s how different seam types compare:
Example: The Arc’teryx Cormac Crew uses merrow stitching and is considered one of the most comfortable running shirts for all-day use. Meanwhile, the ON Performance-T uses extensive taped seams but feels stiff and restrictive at the neck and back panels—showing that even premium seam technology needs careful execution.
Falke Core Speed: This shirt uses a one-piece main body with virtually seamless construction to minimize chafing risk, combined with a barely-there flat collar and taping at the back of the neck to keep it in place.
Fit Considerations
Fit is incredibly variable from person to person, but good running shirts generally balance freedom of movement with a streamlined silhouette.
| Fit Style | Characteristics | Best For |
|---|---|---|
| Athletic/tapered | Fitted through shoulders and chest, relaxed at hem | Performance running, racing |
| Relaxed | Looser throughout, more airflow | Hot weather, casual runners |
| Semi-fitted | Balanced, neither too tight nor too loose | Versatile training, all-around use |
Example: The Falke Core Speed has a snug fit across shoulders and chest with a loose hem—which means excellent freedom of movement but may feel “baggy” to some runners.
Key design principle: “Unitefit” systems (like Adidas uses) are designed to work across different body types while maintaining consistent performance.
Sleeve Design
Sleeve cut affects both movement and aesthetics.
Example: The Falke Core Speed features “high-cut sleeves” that reviewers say “leaves plenty of freedom to move”.
Ventilation Technologies: How to Keep Runners Cool
Good running shirts breathe. Here are the most common ventilation technologies:
1. Laser-Cut Perforations
How it works: Laser technology cuts tiny holes directly into the fabric, providing ventilation exactly where it’s needed—underarms, back, and chest.
How it’s produced: Laser cutting creates clean, sealed edges that won’t fray or distort. It’s highly precise and can be automated for consistent results across production runs.
Pros:
- Targeted ventilation in high-sweat zones
- No added weight or bulk
- Precise, consistent hole size and placement
Cons:
- The backside can be rough or less smooth—the laser-cut edge, while sealed, can feel slightly abrasive against the skin
- Adds manufacturing step and cost
- Requires specialized laser cutting equipment
Application: Used in performance running shirts, compression gear, and leggings where targeted airflow is critical.
2. Jacquard/Knitted Ventilation
How it works: Ventilation is built into the fabric structure using different knit patterns. The Falke Core Speed uses “different textured panels knitted into the tee” with a “tiny honeycomb perforated section” running down the spine, under the arms, and across the chest.
How it’s produced: Jacquard ventilation is achieved through the knitting process itself—no post-production cutting required. The ventilation pattern is built directly into the fabric construction during manufacturing.
Pros:
- Seamless, integrated ventilation
- More durable than cut holes (no fray risk)
- Can be designed for specific body zones
Cons:
- Higher MOQ (Minimum Order Quantity)—typically fabric minimums start at 1 ton (1000kg)
- Limited to the knits the factory can produce
- Higher tooling/setup costs
Application: Premium running apparel with integrated performance features.
3. Laser-Engraved/Etched Ventilation
How it works: Laser engraving creates surface texture and shallow ventilation channels directly onto fabric without cutting through completely. Used for adding breathable zones in specific areas.
How it’s produced: A non-contact process that maintains material durability while creating ventilation patterns.
Pros:
- Adds breathability without weakening fabric
- Can create intricate ventilation patterns
- Maintains fabric integrity
Cons:
- Requires access to laser engraving equipment
- Higher setup costs
- Best for premium/large-volume orders
4. Mesh Panels / Woven Vents
How it works: Separate mesh or open-weave panels are sewn into high-sweat areas (underarms, back, side panels).
Pros:
- Can be added to any shirt design
- Simple, well-understood technology
- Affordable and reliable
Cons:
- Adds seams (potential chafe points)
- May affect overall garment durability
- Less integrated than jacquard or laser-cut approaches
Example: The REI Swiftland T-Shirt uses side vents for improved airflow.
Logo Placement and Customization Options
How your logo appears on the shirt matters—for brand visibility, for runner safety, and for aesthetic appeal.
Common Logo Placement Options
Logo Application Methods
Safety and Reflective Logos
Visibility is a key selling point for running apparel—especially for runners who train in the morning or evening.
What to look for:
- Reflective logo printing—like Nike’s “Flash” line with logos printed in reflective ink
- Reflective panels integrated with the logo design
- Full reflective branding elements on both front and back
Example: Under Armour’s Velociti Flash Logo shirt features a reflective logo on a soft cotton-poly blend designed for running. Nike Run Division uses reflective graphic prints across sleeves, chest, and back.

Pros: Soft, light, high-cut sleeves for free movement, good moisture management, virtually seamless.
Cons: Fit may be “baggy” or “floaty” for some, high hem leaves midriff exposed on some body types.
Nike Dri-FIT Run Division Rise 365
Design features: Reflective graphic prints on sleeves, chest, and back; lightweight, breathable fabric.
Pros: High visibility, premium run-focused design.
Cons: Premium price point.

Practical Advice for Brands
Small Orders (Under 100-300 pieces)
Key takeaway: For small orders, laser-cut perforations and heat transfer logos are the practical choices. They give you functional ventilation and branding without requiring massive fabric commitments.
Medium Orders (300-1000 pieces)
You can start exploring:
- Laser-cut perforation for logos—available at this volume
- Combination approaches: Reflective logo + laser-cut ventilation holes
- Sublimation for all-over design—available at low MOQ (often 1 piece minimum in some factories)
Large Orders (1000+ pieces)
This is when you can consider:
- Jacquard/knitted ventilation—requires fabric MOQs starting at 1 ton
- Proprietary fabric blends with built-in designs
- Fully customized patterns and placements
Note: Some basic models use 220gsm 100% polyester fabric and support small-batch heat transfer logos at low MOQ—a practical starting point for new brands.
